Abstract

The present invention is provided with a rotational axis (18), a curving operation knob (4), a fixed axis (10), two movable disks (11, 12), a fixed disk (14), a cam member (15), a resistance providing member (17) and a fixed lever (5). The resistance providing member (17) comprises a swinging portion (17t) which is swingable in a radial direction and which fixes the rotational position of the cam member (15) at a second position of the movable disks (11, 12) by abutting with added force against the inner circumferential surface of a protruding portion (15t) of the cam member (15) which moves in accordance with the rotation of the cam member (15) in one direction.

Description

technical field [0001] The present invention relates to a bending operation device for an endoscope that is provided in an operating portion of the endoscope and bends a bending portion of an insertion portion of the endoscope. Background technique [0002] In recent years, endoscopes have been widely used in the medical and industrial fields. The endoscope used in the medical field can observe the organs in the body cavity by inserting the elongated insertion part into the body cavity of the subject, and if necessary, use the Various treatments are performed through the treatment instrument inserted into the channel. [0003] In addition, the endoscope used in the industrial field can damage and corrode the inspected part in the inspected body by inserting the elongated insertion part of the endoscope into the inspected body such as jet engine or factory piping. and other observations or inspections of various treatments. [0004] Here, there is known a configuration in ...
